Bridging: Loop detection for Layer 2 network

We've expanded loop detection to Layer 2 (L2) networks, regardless of whether EVPN is configured or not. In earlier releases, we supported enhanced loop detection only in EVPN-VXLAN networks. This feature detects the following types of Ethernet loops:

• A loop between two interfaces in different Ethernet segments (ESs). This loop is typically caused by miswiring fabric components.
• A loop between two interfaces with the same Ethernet segment identifier (ESI). This loop is typically caused by miswiring a third-party switch to the fabric.

To enable loop detection for a logical interface or for all logical interfaces, use the loop-detect statement at the [edit protocols] hierarchy level.
